QuestionAnswer
People who study weather are called ______. meteorologists
The mixture of gases that surrounds the Earth is called the ______. atmosphere
High-pressure belts of air that flow very rapidly from west to east at altitudes above 12 km are called _____. jet streams
The amount of moisture that the air holds compared to the amount it can hold at that temperature is expressed as a percent called ______. relative humidity
The sprinkling of substances into clouds to produce precipitation is called ______. cloud seeding
The ozone layer protects the Earth by absorbing ultraviolet rays
The Greenhouse Effect is due largely to carbon dioxide
A barometer is used to measure air pressure
In the northern hemisphere, the coriolis effect causes winds to curve to the right
Winds in the far north that appear to travel from east to west are called polar easterlies
Van Allen belts are made up of ______. protons and electrons
The Aurora Borealis occurs because of charged particles trapped in the ______. ionosphere
The solar wind is made up of ________. ions
The area around the earth that extends beyond the atmosphere is _______. magnetosphere
The protective layer of the atmosphere that absorbs most of the harmful ultra-violet radiation from the sun is made of ozone
Artificial satellites orbit the Earth in the ______. exosphere
The layer in which radio waves are bounced back to the earth is the ionosphere
Ultraviolet rays and x-rays cause charged particles to form in the ionosphere
The upper thermosphere is called the ionosphere
The division between the lowest layer and the second-lowest layer of the atmosphere is called the tropopause
The lower thermosphere is called the ionosphere
The layer of the atmosphere in which temperatures are lowest is the mesosphere
The jet stream occurs in the lower part of the stratophere
The layer of the atmosphere in which temperatures are are the highest is the troposphere
Almost all the Earth's weather occurs in the troposphere
The second-lowest layer of the atmosphere is called the stratophere
The lowest layer of the atmosphere is called the troposhere
The atmosphere is divided into layers according to major changes in temperature
Scientists are concerned that the burning of fuels is increasing the amount of atmospheric carbon dioxide
Approximately what percent of the earth's present atmosphere is nitrogen? 78
Large clouds that produce thunderstorms are called stratus clouds False, cumulonimbus
Balls or chunks of ice ranging in diameter from 5 to 75 mm and falling as precipitation are called hail. True
During the summer, continental polar air mass forms over Mexico and brings, hot dry air to the southwestern U.S.? False, continental tropical
Small lines at the end of the shaft that represents wind direction on a weather map indicate wind speed. True
The symbols indicating current weather conditions at a weather station is called a station model. True
Radiant energy does not need the presence of solids, liquids or gas in order to travel. True
Air pressure varies according to the density of the air. True
A wind vane is used to determine wind speed. False, wind direction
The flow of air from the land to the sea is called a sea breeze. False, land breeze
The temperature at which water vapor condenses is called dew point. True
Why do hurricanes form over tropical oceans? Hurricanes are powerful cyclones. A low pressure forms over warm water. Warm moist air begins to rise, cooler air moves in, the air begins to spin
What is the sling psychrometer used for? To measure relative humity
Compare and contrast the desert and tropical climates. Desert-little rain hot temps, sparse plant and animal life Tropical-lots of rain, hot temps, wide variety of plant and animal life
